Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its halogenated structure makes it suitable for cross-coupling reactions, such as Suzuki or Ullmann reactions, enabling the construction of complex biphenyl derivatives. Commonly employed in the development of liquid crystals and organic semiconductors due to the stability and electronic properties imparted by the biphenyl core and halogen substituents. Also finds use in research settings for the preparation of ligands and functional materials. Handle with care due to its toxicity and potential for bioaccumulation in the environment.
